After I installed socketcand in ubuntu, when I executed "socketcand -i can0", it was an error "bind: Cannot assign requested address".
I could use can-utilis, like cansend and candump, etc.
What is missing?

I'm have trouble with ./configure
I'm geting Error

I discovered that socketcand on the embedded side does NOT recognize cannelloni on my VM, which has pass-through mechanisms between VM on PC and embedded HW (Beaglebone Black).

What I do, I set in my VM my private network, which sees all the components (energenie switch, bbb board and VM eth2 interface with built-in DHCP and TFTPD-hpa which work perfectly).

On the VM, I have the following set:

lsmod | grep can
vcan 16384 0
can_gw 20480 0
can_dev 24576 0
can_bcm 24576 0

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

True CAN-Fd vcan0 interface.

The VM private IP eth2 looks like:
eth2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.15.2 netmask 255.255.255.0 broadcast 192.168.15.255

TX packets 103432 bytes 65516832 (62.4 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

NMAP command gives me the following:
nmap -T5 -sP 192.168.15.0/24

Starting Nmap 7.40 ( https://nmap.org ) at 2018-08-14 12:59 GMT

Nmap done: 256 IP addresses (4 hosts up) scanned in 1.70 seconds

So, my BBB IP is 192.168.15.101 !

The VM Cannelonni is configured as:
cannelloni -I vcan0 -R 192.168.15.101 -r 28601 -l 28601&

On the BBB side, I have very similar VCAN interfaces, and similar VCAN0 CAN-Fd capable interface.

But I am not able to connect with the command:
socketcand -v -i vcan0 -p 28601 -l eth0&

My best guess is that beacon is working, but I do NOT see any receiving CAN-Fd packets which Cannelloni sends to 192.168.15.101 , port 28601.

And here is the CLI transcript what I did on the BBB side:

root@beaglebone:~ ps -aux | grep socketcand
root 1607 0.0 0.2 10196 1324 pts/0 Sl 12:07 0:00 socketcand -v -i vcan0 -p 28601 -l eth0
root 1656 0.0 0.2 2776 1208 pts/0 S+ 13:05 0:00 grep socketcand
root@beaglebone:~ nc 192.168.15.101 28601
client connected
< hi > < open vcan0 >
connecting BCM socket...
< ok > < rawmode >
state changed to 2
< ok >

And I do NOT see any received packets. neither any beacon discovery.

I have here two questions about this problem:
[1] Does socketcand recognize cannelloni CAN packets? If not, why, and how to rework socketcand, so it could be achievable?
[2] Does any another socketcancl (socketcan client) exist which is compatible with socketcand?

Please, help!

Thank you,
Zoran Stojsavljevic

It would be nice to have bus name aliases in the discovery beacon. This would help the user to recognize busses.

Hi All,

Tried to compile socketcand for ARM processor, used cross compilation, added below lines in Makefile
CROSS_COMPILE = arm-linux-gnueabihf-

Hi, I try to establish CAN communication between a java application (running in virtual machine Ubuntu 14.04) and a device using CAN/USB convertor (http://www.systec-electronic.com/en/products/industrial-communication/interfaces-and-gateways/can-usb-adapter-usb-canmodul1). The java application uses kayak-core to send CAN frames. When the driver is loaded and the bitrate is set properly, the java application is started and the communication works fine. However after a while the communication stops working. The CAN/USB convertor does not indicate any error, the java application runs without any warning, however the CAN bus is silent (no messages transmitted or received by the java application). When I try to send a single CAN message from linux terminal using "cansend can0 100#00" command it says "write: No buffer space available". It seems that it is problem of socketcan, does it not? Can you give me an advise how to fix this issue?

I use these commands

1. load driver and set bitrate
   sudo modprobe can_raw
   sudo modprobe can_dev
   sudo make firmware_install
   sudo insmod systec_can.ko
   sudo ip link set can0 up type can bitrate 125000
2. provide access for can0
   socketcand -i can0

The details and statistics of can0 are:

17: can0: <NOARP,UP,LOWER_UP,ECHO> mtu 16 qdisc pfifo_fast state UNKNOWN mode DEFAULT group default qlen 10
link/can 00:04:cb:18:00:00 brd 00:00:00:00:00:00 promiscuity 0
can state ERROR-ACTIVE restart-ms 0
bitrate 250000 sample-point 0.875
tq 250 prop-seg 6 phase-seg1 7 phase-seg2 2 sjw 1
systec_can: tseg1 1..16 tseg2 1..8 sjw 1..4 brp 1..255 brp-inc 1
clock 48000000
re-started bus-errors arbit-lost error-warn error-pass bus-off
0 0 0 0 0 0
RX: bytes packets errors dropped overrun mcast
766656 95832 0 0 0 0
TX: bytes packets errors dropped carrier collsns
354108 95831 0 0 0 0

If too many frames will be sent over the SocketCAN interface, send() comes with -1 and errno is set to ENOBUFS. Some of the can-utils (cangen) provide extra option to ignore this error. If such an error occurs cangen would just resend the CAN frame in question.

This question (http://dics.voicecontrol.ro/process_mails/arata_discutia/173374/[PATCH]_candump:_add_option_to_ignore_ENOBUFS.html) was once brought up on the linux-can mailing list, but still there is no official solution for this issue.

Hi

I try to use the socketcand with java kayak test class but i m facing a problem :

client connected
client try to acces unauthorized bus

Does someone know what to do please ?

candump can0 & can send working on the Rpi.

Compiled on Fedora using all current developmental headers.
Code:
sudo modprobe vcan
sudo ip link add dev vcan0 type vcan
sudo ip link set up vcan0
socketcand -i vcan0

Output:
Error in beacon send()

must terminate with Ctrl+C.

Hi,
I get successfully CAN-utils working. Also, built SocketCand without any errors.
When I try to connect to socketcand from putty / telnet, it always gives me "< hi >" but when I finish my command and press Enter, the connection is lost.
Please advise.

Regards,
DN

Hello,

I am writing the recipe for the socketcand package. It looks so far very simple:

PR = "r0"

RDEPENDS_${PN}-dev += "${PN}-staticdev"

SRCREV = "df7fb4ff8a4439d7737fe2df3540e1ab7465721a"

SRC_URI = "git://github.com/dschanoeh/socketcand.git;protocol=http"

S = "${WORKDIR}/git"

inherit autotools

I did install the following:
sudo apt-get install autoconf
sudo apt-get install libconfig-dev

The error is in do_config():

| checking for config_init in -lconfig... no
| configure: error: in
`/home/netmodule.intranet/stojsavljevic/projects/beaglebone-black/yocto-rocko/poky/build/tmp/work/cortexa8hf-neon-poky-linux-gnueabi/socketcand/1.0-r0/build':
| configure: error: config test failed (--without-config to disable)

What should I include in the recipe to make it work (both autoconf
and ./configure work normally for the normal installation)???

Thank you,
Zoran

when i run it like this : socketcand -v -i wlan0 -p 29536 -l 192.168.16.112 ,it report "Error in beacon send()" ,what does this mean ? i run it on my laptop by the way . Is this a bug ?

Is it correct that socketcand does not support the data-communication protocol CAN FD (CAN Flexible Data Rate)? Or did I miss something?
CAN FD frames created with can-utils are not displayed in raw mode.

dschanoeh,

The help for socketcand doesn't really describe how it works or the basic usage pattern. Do both ends of the can bus (real or virtual) spawn a socketcand instance? Can you provide a simple end-to-end example with two vcan interfaces?

My goal is to use socketcand to proxy a can/vcan device over ethernet.

Here is what I'm trying:

$ ./socketcand -i vcan0 -v -l lo -p 12345 &
$ nc 127.0.0.1 12345
< hi >< open vcan0 >
< ok >< rawmode >
$ cangen vcan0 &
$ tcpdump -nni lo udp

Should I be seeing traffic on lo? I'm seeing a bunch of output in the socketcand window, but obviously no traffic on my network interface.

Any help is appreciated!

Issue never existed.
